SQL Practice Assistant / SQL 练习助手

Security checks across malware telemetry and agentic risk

Overview

This does not look like malware, but it is a promotional and under-specified skill that does not provide the SQL practice assistant it advertises.

Review this carefully before installing. It appears low-risk from a malware perspective, but it mostly contains marketing and affiliate links rather than a usable SQL practice skill, and it requests curl without showing a need for it.

Description-Behavior Mismatch

Medium
Confidence
93% confidence
Finding
The skill metadata advertises a SQL practice assistant, but the body of the skill contains only generic marketing copy, pricing, affiliate links, and contact information with no actual SQL-practice behavior, instructions, or safeguards. This mismatch is dangerous because users or automated systems may install or trust the skill based on false claims, enabling deceptive distribution, policy evasion, or later substitution with harmful behavior under an innocuous educational label.
